The Lowdown

Alright, let's get into it. The outlook for the next couple of weeks here is a real slow burn. We're looking at a long stretch of flat, weak, and messy conditions before anything worth paddling out for shows up. It's going to be a test of patience.

Right now, Kennebunk Beach is offering nothing. The first few days are a write-off. Saturday the 5th has a tiny 2ft east swell, but it's weak and the wind is cross-offshore. The combined energy is a measly 49, so there's just no push. The water temp is sitting at 65°, which is a touch warmer than normal for this time of year, but that's about the only thing going for it.

We then hit a real dead zone. From Sunday the 6th all the way through to Wednesday the 16th, it's a desert. The swell hovers around 0.3ft to 1ft most days, the wind is often onshore or cross, and the energy readings are pathetic, mostly double digits. There's a brief moment on Friday the 11th afternoon with glassy conditions, but the swell is still only 1.0ft – you could float a toy boat, but not much else. Saturday the 12th and Sunday the 13th are similarly hopeless. Monday the 14th afternoon throws up a 3ft wind swell from the south with a period of 4 seconds, meaning it's just bumpy, junky, and short-period chop. Not worth it.

The only light at the end of the tunnel comes on Thursday the 17th of September. A pulse of swell arrives, with 8ft from the ENE in the morning and 7ft from the E in the afternoon. The period is 7-8 seconds, so it's a wind swell, but the energy jumps to 583. That's a solid kick. The wind is light, but it's cross or cross-onshore, so it's going to be a bit lumpy. The forecast says "marginal," and honestly, at over 7ft at a beach break like this, it's pushing into expert territory. It won't be clean, but it's the first real sign of life.

The real standout comes on Friday the 18th of September. We've got a 5ft east swell in the morning with a 9-second period and a combined energy of 402. That's a solid, moderate groundswell. The wind is light and cross-offshore from the ENE, which will keep it clean. The swell drops to 5ft in the afternoon, still with decent energy. This is the best on offer in the entire 16-day window. The water will still be warm, and the wind is light, so it should be a fun session. It won't be huge, but it'll be the most rideable and cleanest conditions we'll see.

After that, it drops off fast. Saturday the 19th is onshore and messy, and Sunday the 20th is a write-off with strong offshore wind but a tiny 3ft swell.

So, to sum it up: you're waiting for Friday the 18th of September. That's your day. The rest of the time, you're better off checking the tides for a sandbar or finding a new hobby.

Information about the Kennebunk Beach Surf forecast

The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
